1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Introduction: Ischemic stroke is a devastating neurovascular condition that occurs when cerebral tissue fails to receive an adequate supply of oxygen. Despite being a leading cause of death and disability worldwide, therapeutic interventions are currently limited. Polyamidoamine (PAMAM) dendrimers are nanomolecules commonly used in biomedical applications due to their ability to encapsulate small-molecules and improve their pharmacokinetic properties. Curcumin is known to have anti-inflammatory and antioxidant effects yet suffers from poor solubility and bioavailability. The purpose of this study is to investigate the efficacy of curcumin encapsulated in PAMAM dendrimers as a potential therapeutic treatment for ischemic stroke by studying post-stroke lesion size, astrocyte reactivity, and functional recovery in a rat model of cerebral ischemia. Methods: Forty-eight male and female Sprague-Dawley rats (280-380 g) underwent either a 90-min middle cerebral artery occlusion (MCAo) or sham surgery before receiving one of four treatments: (1) Hanks' balanced salt solution (HBSS) control, (2) empty dendrimer control, (3) curcumin control, or (4) curcumin encapsulated in PAMAM dendrimer. Neurobehavioral outcomes were evaluated at 1-, 3-, 5-, and 7-day post-surgery, after which animals were euthanized on day 8 to assess infarct volume and GFAP immunoreactivity. Results: Animals that received formulations containing dendrimers (curcumin encapsulated in dendrimers or empty dendrimers) demonstrated significantly lower levels of GFAP immunoreactivity and improved functional recovery, including weight and neurobehavioral scores, compared to the formulations that did not contain dendrimers (curcumin and HBSS control). Additionally, the dendrimer-curcumin treatment group exhibited a significantly improved paw laterality index over the course of the study compared with the other three treatment groups. Conclusion: Although the post-stroke administration of curcumin encapsulated in PAMAM dendrimers modulates the astrocytic response and promotes functional recovery following ischemic stroke in rats, its therapeutic benefits may be driven by PAMAM dendrimers as the empty dendrimer treatment group also showed significant improvements post-stroke. Further investigation regarding PAMAM dendrimers in treating neuroinflammatory conditions remains warranted.
